Loading Cisco IOS using TFTPDNLD !

Suppose you lost your Cisco flash memory and you need to download a new IOS using ROMmon mode, my Friend Ahmed Magdy who is my Cisco instructor as well, gave me the following instructions.

Step 1:Put your TFTP Server and Cisco router on a LAN segment. You should know TFTP Server IP address, IOS image name, Subnet mask of the network which your TFTP Server is connected to, and if your router is not connected to the same LAN of your TFTP Server you should use the gateway address as well.
